Given numbers are 493,559,645,725
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,559,645,725 is 20669025.
Find LCM of 493,559,645,725 with Prime Factorization
| 5 | 493, 559, 645, 725 |
| 29 | 493, 559, 129, 145 |
| 43 | 17, 559, 129, 5 |
| 17, 13, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 43 x 17 x 13 x 3 x 5 = 20669025
Therefore, the lowest common multiple of 493,559,645,725 is 20669025.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
493 x 559 x 645 x 725 = 128871370875
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
493 : 1, 17, 29, 493
559 : 1, 13, 43, 559
645 : 1, 3, 5, 15, 43, 129, 215, 645
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,559,645,725, is 1.
Now, the common factors can be found like this.
493:17x 29
559:13x 43
645:3x 5x 43
725:5x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 29x 43 = 6235
Therefore, the value for common factors is 6235.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 128871370875/(1x6235)
LCM = 128871370875/6235
LCM = 20669025
Thus, we can understand that the LCM of 493,559,645,725 is 20669025.
